Answers

Answer:

48

Step-by-step explanation:

18 less than half a number is 6.

So this is the formula:

X/2 - 18 = 6.

You can add 18 to 6.

X/2 = 24.

You can now multiply by 2.

X=48

Solve and show your work below: Julie And Paulo are building a treehouse. Julie has a wood board that is 1.15 meters long and Paulo has a board that is 0.7 meter long.What is the total length of the two boards ? Solve this problem any way you choose .

Answers

Answer: Total length of the two boards= 1.85 meters

Step-by-step explanation:

Given: For a treehouse

Length of first wooden board =  1.15 meters

Length of second wooden board = 0.7 meters

Then by using the addition operator

Total length = Length of first board  + Length of second board

= 1.15 + 0. 7 meters

= 1.85 meters

Hence, the total length of the two boards = 1.85 meters

Answers

Sorry this got to you super late. At least others looking for the answer can find it.

The proof by S A S congruence rule is given below.

Given from fig, JK || LM.

And JK = LM

Since JK is parallel to LM and JN is a transversal so the angle made on the same side of JN are corresponding angles which are equal to each other.

So, angle KJL = angle MLN........equation 1

Also given L is the midpoint of JN so, JL = NL.....equation 2

Now, in triangle JLK and triangle LNM

JK = LM (given)

angle KJL = angle MLN (from 1)

JL = NL (from 2)

So by S A S congruence rule, triangle JLK conguent triangle LNM proved.

what is the y and x intercept of 15x + 20y =1800?​

Answers

You can do this by doing 1800 / 15 which is 120 and 1800 / 20 which is 90
Which means that the x intercept is 120 and the y intercept is 90.
For the y-intercept equation, the x will always be 0. And vice versa.

20y = 1800
Divide by 20 on both sides

y = 90

15x = 1800
Divide 15 on both sides

x = 120

A bowl with 2 cups of flour in it weighs 405 grams. When it has 5 cups of flour in it, it weighs 765 grams. How much does the bowl weigh by itself?

Answers

Answer:

im think the bowl weighs 49.5 grams by itself

Step-by-step explanation:

405/2= 202.5

765/5=153

202.5-153=49.5

9514 1404 393

Answer:

  165 grams

Step-by-step explanation:

We can write an equation for the total weight (y) as a function of the number of cups of flour (x). The y-intercept of that equation will be the weight of the bowl.

The two-point form of the equation of a line is ...

  y = (y2 -y1)/(x2 -x1)(x -x1) +y1

The two points we are given are (2, 405) and (5, 765).

  y = (765 -405)/(5 -2)(x -2) +405

  y = 360/3(x -2) +405 . . . . simplify a bit

  y = 120x -240 +405 . . . . . eliminate parentheses

  y = 120x +165 . . . . . . . . . . combine terms

The bowl by itself weighs 165 grams.

__

Each cup of flour weighs 120 grams.

Hope I get brainliest (:

The addition is one of the four fundamental mathematical operations. The total time that is taken by the train to reach Chittagong from Dhaka is 9 hours and 20 minutes.

What is Addition?

The addition is one of the four fundamental mathematical operations, the others being subtraction, multiplication, and division. When two whole numbers are added together, the total quantity or sum of those values is obtained.

Given that train left Dhaka train station at 10:30 pm. Therefore, the time from 10:30 pm to 12 a.m is 1 hour 30 minutes.

Further, the train arrived at Chittagong train station at 7:50 am the next day. Therefore, the time from 12 a.m to 7:50 am is 7 hours and 50 minutes.

Further, the total time that is taken by the train to reach Chittagong from Dhaka is,

Time = 1 hour 30 minutes + 7 hour 50 minutes

        = 9 hours and 20 minutes

The side given is 110*, and the side underneath that is 90*. If you add it together, That's 200*. Due to the sum property of a quadrilateral, we know that the angles must add up to 360* in total. So, we can simplify it as following.

(2x) + (x+10) = 360-200

2x + (x+10) = 160

2x + x = 160-10

2x + x = 150

x = 50

Triangle ABC undergoes a transformation using the rule (x,y) → (x + 7. y + 3) to form triangle A'B'C'. Determine if ABC is
congruent to A'B'C'. Explain your reasoning.

Answers

Answer:

ΔABC and ΔA'B'C' are congruent, by the SSS rule of congruency

Step-by-step explanation:

The given parameters are;

The transformation undergone by triangle ABC = (x, y) → (x + 7, y + 3) to give triangle A'B'C'

Therefore, the points on triangle ABC are transformed by a translation of 7 units to the right and 3 units up to form triangle A'B'C'

Given that a translation transformation is a form of rigid transformation, we have;

The lengths of triangle ABC are congruent to the lengths of the sides of triangle A'B'C'

Therefore. ΔABC ≅ ΔA'B'C', by the Side-Side-Side (SSS) rule of congruency.

The graph shows a line of best fit because the points fit around the line.

The graph shows a line of best fit because there is a straight line.

The graph shows a line of best fit because the association is zero.

The graph shows a line of best fit because the points are plotted evenly above and below the line.

Answers

Answer:

The graph shows a line of best fit because the points are plotted evenly above and below the line.

Step-by-step explanation:

The best explanation is that the graph shows a line of best fit because the points are plotted evenly above and below the line option (D) is correct.

What is the line of best fit?

A mathematical notion called the line of the best fit connects points spread throughout a graph. It's a type of linear regression that uses scatter data to figure out the best way to define the dots' relationship.

[tex]\rm m = \dfrac{n\sum xy-\sum x \sum y}{n\sum x^2 - (\sum x)^2} \\\\\\\\rm c = \dfrac{\sum y -m \sum x}{n}[/tex]

We have a line of best fit shown in the picture.

As we know if the slope of the line is positive then the correlation will be positive.

From the line of best fit:

Because the points are evenly spaced above and below the line, the graph displays a line of best fit.

Thus, the best explanation is that the graph shows a line of best fit because the points are plotted evenly above and below the line option (D) is correct.
